' Patented April 9, 1907.

Application filed February 1906 Serial No. 802,743-

thewheel moves along the ground. In .ac-

complishing this object I use two fellies in the construction of this wheel, one within the other, and between them I arrange a new and novelsystem of springs which take up the jolt and jar given the outer felly'and its tire and leave the inner felly'comparatively free from these irregular motions and prevents the :transmission' of same to the axle and -'vehicle., These and other objects and details vof the invention are more fully described in the following specification and set .forth in the appended claims. I 1

In the drawings accompanying this specification and forming apart thereof like refand their ends drawn together by-means'of .erence characters areused to designate the same. parts in the various figures, and Figure 1 isa side elevation oienough of a wheel to clearly illustrate my invention. Fig. 2 is a cross-secti on on the line 2 2 of Fig. 1. Fig. 1 is a c'rossfictionof-"a modified form of construction, and Fig. 4 is a detail of one of the spring members connectingthe two follies.

The two fellies 5 and 6 are concentric Wi th each other, the inner one, 5, receiving the -outer ends of the spokes 7 and is embraced by a metal ring 8, which is depressed at certain points 9, as'shown in Fig. 4. These depressions 9 inthe ring-8 are adapted to receive leaf-springs 10, made up of several sections,-but preferably three, as shown in the drawings, and are held'rigid with the folly 5 by means of clips '11, which are more clearly shown in Fig. 2, where they' will be seen to embrace the felly and leaves of the spring 10,

the bolts 12. These clips are held in place and the springs 10 are also more rigidly gmited to the felly by. means .of bolts 13, which pass through the springs and folly, and whose heads 14 occupy the space between the ends of the clips 11, while the inner ends of thebolts have nuts 15, which bind these parts and the ring 8 firmly together.

' through the sprin eye-plates 16, Whioh are secured. to said ends place, but also add strength and 'rigi the springs. The construction of these clips -17 is more'clearl. shown in Fig. 4, whreI e inner leaf by means of clips '17,, that not only bind these eye-platesto their proper ity to have shown two orms; but it is obviousthat any simple construction ma. be used to. ac"- complish this end. 'In the oft-hand clip in this figure the same is shownas constructed with three sides, two of which embrace the edges of the leaves of thesprings, while the third or uniting side is held firmly against the side of the outer leaf by means of a bolt 18, which passes through said side of the clip and is provided with a sleeve of hard metal 16 (shown in dotted lines) where it passes middle and the outer leaf of the The lateral screws 19 pass from the sides of the clip into the eye-plate. and add to the security of this attachment. In the modified form at the right-hand side of the spring 10 I show a clip. 17, which embraces the leaves of the springs and the eyeeplate 16, and the two outer leaves of the spring are slotted to ing-through-the eye-plate and inner. side of the clip and carrying on its outer endthe It-is evident that required in the attachment eye-plate to the spring.v For this reasonl dont confine myself to the ordinary simple methods which might be adopted necessarily to the form shown, even stronger means may be adopted to join the severe strain to which devices of this nature are submitted. s

Working in conjunction with the eyeplats 16 are hinge members 20, which are perforated to receive the bolts 21, that-also pass through the eyes of the plates 16and afford a rocking means at the ends of the springs 10. This hinge member 20 has an ofiset at its'upper end which engages a latreceive the head. of a' bolt 18, the said head resting upon the inner leaf of the spring, pass-- great. strength is which secures the these parts to withstand eral socket 22 at the side of the eye-plates 1.6,

that receives the ends of the inner leaf of the spring 10 and at the same time cooperates with' said end of the hinge member to form a stopfor the retractile action of the springs 10 and 3 1,while the outward movement of the ends of the springs is not restricted. The lower ends of these hinge members 20 are perforated to receive'bolts 23, and connected with the I to same-is a link 24, having perforated ends I which receive bolts 26 and 27', that passthrough the. ears of plates 28 and 29, secured to shoes 30, which are carried as a felly at intervals around its circumference, as shown in Fig. 4. It is very evident that when. the spring 10 is compressed the hinge member yields and bends outward, accommodating the increased length ofthe spring,and-. the large bearing-surface of the shoes 30 firmly secure these'pants to the outer felly and give the whole a substantial and rigid constructioIi. The shoes 30 are fiat-bottomed steel boxes having parallel sides which hug the inner edge of the felly 6 and aided by the tension of the spring 10 and 31 forming in itself a stifi but yielding ring normally circular in form in consequence of the pressure of the springs. f v

The bolts 21, which pass through the eyes of the plates 16 and the hinge members 20, also carry the hook ends of a coil-spring 31, which is under tension, and when the wheel is depressed at this point and the springs 10 are depressed this c'oilspring 31 is also acted upon and putunder greater tension, the tendency of the two springs being to return-to the normal position'illustrated in thedrawings.

As shown in Figs. 2 and 3, this spring in crosssection is not necessarily a true circle, but more oval. This enables me to employ s rings whose straightportions have not had t ieir strength nor resilient qualities injured by the convolutions of which the average spring is composed and also allows me to utilize the space provided to the greatest advantage, the said oval construction enabling me to use a spring which would fill nearly the ble and flexiblematerial. -For convenience of illustration this apron is not shown in Fi 1. As shown in Fig. 2, the inner end of this apron is secured to thoi nner felly by means of segmental plates 33 and having screws 34 to secure them to the folly. The outer edge of this apron is clamped between the'circular edge 33 of the rubber tire 34 and the side faces of the shoes or sections 30, the rubber 6o tire havin its body made up of the usual fabric, whi e vulcanized within near its outer surface are a number of wires 35, having in -f turned ends which brace and strengthen the circular edge 33.

"The sections 36 of the felly 6 .is of leather in .eflectually. to the tire.

' carrying the tire, a flat spring order to give due protection to the rubber tire 34, and on the outer surface of tliefleather tire '36- are metal plates 37, encircling the whole at intervals and of about the length of I its companion shoe in order to give the necessary protection which the leathei'r 'and rubbr could not otherwise stand t'he inter.

*vening spacebetweenthe plates being adapted to allow the resilient action of :the leather to assertitself. These three sections 34, 36,

and 37 are rigidly secured together by" screws 38 and a bolt 39, the latter passin through all the sections and the other one o the shoes'28 or 29,;where' a nut 40 serves to bind them all together and secure the springs In Fig. 3 I show a modified form of the wheel in cross-section and in which a thin flat spring steel hoop 25 lies on the inner side of the felly and on same the shoes 30 lie. This hoop 25 is adapted to keep the flexible felly circular in form, acts as a further aid to resiliency, and maintains lat-- -eral'rigidity of said felly, and yet allows the inward and outward movement of the sectional parts 30. Superimposed upon said hoop and maintained in position by the side's of the shoes or sections 30 are rings of cotton web 44 and leatherrings 41, 42, and 43, and iron plates 45, one-plate over each shoe'30, the whole .making a firm and flexible tire impervious to moisture, mud, or grit, the parts 30, 41,42, 43, and 44 being bolted together by the bolt 47 and its nut 48. The

apron in this case has its inner edges se-- curely attached to segmental plates 49, also secured to the inner felly 5 by screws 50, and, being of one piece, has its central portion carried between the leather sections 42 and 43, from which it can be removed bytaking off the plates and the two leather sections plates 49. This wheel is especially able to withstand great lateral strains and the coin- 1. 5 41 and 42 and loosening the screws-in the bined resilient qualities of thespringathe leather and rubber making it an exceedingly easy running wheel, one not liable-to be puhctured or get out of order. In the construc tion of such a wheel various littlemodificar tions in the details here shown can be refrom the broaderein efore described."
